Soldiers of the 4th Battalion, 10th Special Forces Group take on an eerie green glow when seen through night vision lenses as they patrol in boats during exercise Emerald Warrior in Appalachicola, Fla. Emerald Warrior is an annual two-week joint/combined tactical exercise sponsored by U.S. Special Operations Command. It is designed to build on lessons learned from operations in Iraq and Afghanistan to provide combatant commanders with the trained and ready forces they need.

Based at Fort Carson, Colorado with one battalion in Stuttgart, Germany, the 10th Special Forces group is responsible for special operations needs in Europe, from Armenia to Ireland.
